Description

一种矿山井下巷道掘进面移动式通风除尘降温一体化装置Mobile ventilation, dust removal and temperature reduction integrated device for mine tunnel driving face 技术领域Technical field
本发明属于矿山安全与环境工程技术领域,尤其涉及一种矿山井下巷道掘进面移动式通风除尘降温一体化装置。The invention belongs to the technical field of mine safety and environmental engineering, and in particular relates to a mobile ventilation, dust removal and temperature reduction integrated device for the tunneling face of a mine underground.
背景技术Background technique
我国矿产资源丰富,煤炭、金属等矿产资源多采用地下开采的方式。随着我国经济的发展,对煤炭、金属等资源的需求越来越大,浅部资源基本已经开采殆尽,地下采矿需要进一步向深部转移。然而随着开采深度的增加,地层温度也相应增加,从而导致地下资源开采过程中工作环境高温的问题;尤其是井下通风不畅的巷道掘进面,岩石及工作面设备的热量不能及时被带走,致使掘进工作面高温可高达40℃,严重超过了国家标准的规定的值。地下采矿的过程会涉及到大量的煤岩的爆破、破碎等,这会产生大量的煤岩粉尘和炮烟。而地下采矿是在一个相对封闭的空间,只能靠通风来带走工作面开采产生的粉尘、炮烟。而对于独头巷道在掘进过程中的通风不良,就会导致掘进面产生的大量煤岩粉尘、炮烟不能及时的被带走,导致工作面粉尘浓度严重超标、炮烟浓度仅能达到国标的规定情况。my country is rich in mineral resources, and coal, metals and other mineral resources are mostly mined underground. With the development of my country's economy, the demand for resources such as coal and metals is increasing. The shallow resources have basically been exploited, and underground mining needs to be further transferred to the deep. However, as the mining depth increases, the formation temperature increases accordingly, which leads to the problem of high temperature in the working environment during the mining of underground resources; especially in the tunnel driving face with poor ventilation, the heat from the rocks and working face equipment cannot be taken away in time , Resulting in the high temperature of the tunneling face as high as 40 ℃, which seriously exceeds the value specified in the national standard. The process of underground mining involves the blasting and crushing of a large amount of coal and rock, which will generate a large amount of coal dust and gun smoke. While underground mining is in a relatively closed space, ventilation can only be used to take away the dust and gun smoke generated from mining face. As for the poor ventilation of the single-headed roadway during the excavation process, a large amount of coal dust and gun smoke produced at the tunneling face will not be taken away in time, resulting in a serious excess of working dust concentration, and the gun smoke concentration can only reach the national standard. Prescribe the situation.
除了通风不畅会带来深井工作面温度高、粉尘浓度高以外,对于矿井通风网络复杂的矿井,当巷道掘进工作面位于矿井的主要回风侧时,用于供应该掘进工作面的风流中已经混合了上游大量的热量、粉尘和炮烟等,这时候高温且含有粉尘、炮烟的风流如果再供应给该掘进工作,就会进一步加剧该工作面环境的恶化,导致风流温度更高、粉尘、炮烟浓度更高等问题的出现。风流温度过高会导致人员晕厥,粉尘浓度高则会导致人员尘肺病的发生,炮烟浓度高则存在人员中毒的风险。因此,如何降低回风侧巷道掘进工作面风温、粉尘及炮烟浓度,减少对人体的危害,成为了亟需解决的问题。In addition to poor ventilation, which will bring high temperature and high dust concentration in the deep shaft working face, for mines with complex ventilation networks, when the tunnel driving face is located on the main return air side of the mine, it is used to supply the air flow of the driving face A large amount of heat, dust, and cannon smoke have been mixed upstream. At this time, if the high-temperature air flow containing dust and cannon smoke is supplied to the tunneling work, it will further aggravate the deterioration of the working face environment, resulting in a higher air flow temperature. The emergence of problems such as higher concentrations of dust and cannon smoke. Excessive air current temperature can cause people to faint, high dust concentration can lead to the occurrence of people's pneumoconiosis, and high smoke concentration can lead to the risk of personnel poisoning. Therefore, how to reduce the air temperature, dust and gun smoke concentration of the tunnel driving face on the return air side, and reduce the harm to the human body, has become an urgent problem to be solved.
发明内容Summary of the invention
针对上述现有技术存在的问题,本发明提供一种矿山井下巷道掘进面移动式通风除尘降温一体化装置。本发明可以有效的降低回风侧巷道掘进工作面风温、粉尘及炮烟浓度,减少对人体的危害;同时随着巷道掘进工作面向前的推移,该 装置也可以在轨道向前推移,与掘进面保持合适的距离,使用便捷。In view of the above-mentioned problems in the prior art, the present invention provides a mobile ventilation, dust removal and temperature reduction integrated device for the tunnel heading face of a mine underground. The present invention can effectively reduce the air temperature, dust and smoke concentration of the tunnel driving face on the return air side, and reduce the harm to the human body; at the same time, as the tunnel driving face moves forward, the device can also move forward on the track, and The tunneling face is kept at a suitable distance and is easy to use.
